Compensate donors to 100% of lost earnings, with some upper-bound cap so we aren’t paying huge amounts for a very high earner’s kidney (where finances are unlikely to be a barrier to donation anyway);

Route that compensation through the Ministry of Health rather than make donors go through Work & Income;

Compensate those not in employment either as though they were in employment at the minimum wage, or at their last reported earnings were they recently in employment. Those not employed will still incur opportunity costs from donating and may be less able to provide services within the household;

Live donors should receive a guarantee that, should they need a transplant, they will have priority place in the queue. They’ve already shortened the queue by one place by their gift.
